Title: Light plate for vacuum cleaner
Inventor: SUMERAU WILLIAM R
IPC: A47L9/30
Filed: 1988-05-10
Granted: 1991-06-04
Abstract: TITLE:  LIGHT PLATE FOR VACUUM CLEANER                ABSTRACT OF THE DISCLOSURE   A vacuum cleaner main chassis incorporates a light plate for providing light from a relatively narrow slot extending across the front of the chassis onto a floor surface to be cleaned.  The light plate is generally planar and transmits light therethrough within its plane from an input edge of the plate to an opposite output edge thereof.  The plate output edge resides in the chassis front slot while the rest of the plate is enclosed within the chassis so that light emerges from the chassis only through its front slot.  The slot is relatively close to the floor surface for illuminating an area thereof beginning relatively adjacent the chassis.  Lamps located adjacent the relatively rearward input edge of the light plate are thus positioned relatively remote from a suction nozzle and rotatable bar brush located in a forward area of the chassis, which avoids preempting critical space in such area or interfering with operation of such elements. The light plate is also pivotable about an axis located rearwardly of the bar brush, and extends thereacross for pivoting upward to permit access to the bar brush for its removal and maintenance.

Granted: 1992-09-22
Abstract: ABSTRACT OF THE DISCLOSURE            A welding control method is described for automatic welding machines in which the welding gun is moved by a robot successively to a plurality of welding spots on the workpiece where the welding gun is closed to firmly clamp the workpiece while applying pressure thereto and then energized to perform a welding operation.  The welding control method comprises the steps of: closing the welding gun with no work clamped between the electrode tips thereof before actually performing the welding operation at a first welding spot on the workpiece so as to take as a reference the observed degree of opening of the gun arms; storing the observed degree of opening; presetting for each welding spot a specific degree of opening of the gun arms which corresponds to the thickness of the workpiece at that spot; detecting the degree of opening of the gun arms when the welding gun is closed at each welding spot on the workpiece; determining a difference between the detected degree of opening and the reference degree of opening; and comparing said difference with said preset degree of opening to check for any abnormal condition. Abnormal operation of the welding gun can thus be prevented.

Abstract: ABSTRACT OF THE DISCLOSURE An apparatus and method for monitoring the operation of a hollow drive shaft is disclosed.  An instrument is inserted within the shaft.  A first end of the instrument includes an elastomeric retainer having a relaxed outer diameter which is slightly smaller than the inner diameter of the shaft.  The retainer is compressed to expand it into frictional engagement with the inner surface of the drive shaft to retain the instrument therein.  A generator is mounted within the instrument for rotation therewith.  The generator includes a relatively rotatable output shaft having a pendulum attached thereto.  When the drive shaft is rotated, the instrument and the generator rotate therewith, but the output shaft and the pendulum do not. Consequently, an electrical output signal is generated which is representative of the rotational speed of the shaft.  Several sensors are provided to generate electrical signals representative of the torsional stress within the shaft during use and the ambient temperature therein.  The output signals are fed to a control circuit in the instrument.  The control circuit includes a power supply sub-circuit for supplying electrical power to the various components thereof.  The power supply sub-circuit includes batteries for maintaining the supply of electrical power when the drive shaft is not rotated during use and means for re-charging the batteries when the drive shaft is rotated.  A power regulator sub-circuit regulates the electrical power supplied to most of the components of the control circuit.  A wake-up sub-circuit generates a signal when the shaft is rotated.  The control circuit is maintained in an active operating condition when the shaft is rotated and is automatically placed in a stand-by operating condition after a predetermined length of non-rotation.

Abstract: ABSTRACT OF THE DISCLOSURE            Iterative compensation of drift of peak positions of spectral lines in a spectral monochromator including a grating, a detector of  spectral fractions of a spectral band, a stepper motor for varying relative orientation of the grating and the detector, and a computer.  A series of computer-defined spectral windows each encompasses one spectral band and has a nominal spectral position and an initial spectral center.  Each window is scanned such as to determine a peak spectral position.  Calculations are made for a spectral offset of the peak position from the initial center for each corresponding window, an average of the offsets for the peaks as a linear function of window position, and a revised spectral center for each window equal to the initial center plus the average offset for the window position determined from the linear function.  Each window is shifted correspondingly.          The step of successively scanning through each window is repeated such as to determine a new peak position for each corresponding band, whereby each new peak position is maintained near the spectral center of each corresponding window.

Abstract: ABSTRACT OF THE DISCLOSURE       A failsafe method in connection with valve timing-changeover control for an internal combustion engine.  An abnormality in a control system of the engine is detected.  A changeover-instructing signal is generated for changing the valve timing to the low speed valve timing in both of the lower and higher engine speed regions, when the abnormality is detected.  When the abnormality is detected, the air-fuel ratio of an air-fuel mixture to be supplied to the engine is enriched when the engine is in a predetermined operating condition determined by the detected value of at least one engine parameter.  The enriching of the air-fuel ratio of the air-fuel mixture is carried out by multiplying a basic fuel injection period by a correction coefficient or selecting a suitable basic fuel injection period map.
